attach enum typedef source map: %w

Error message

attach enum typedef source map: %w

What it means

EnumTypeDef.AttachDependencyResults got an error back from the attach callback while re-attaching the enum's SourceMap result. The wrap points at dagql dependency hydration failing for the source-map object, not at the enum itself.

Solutions

1. Inspect the wrapped inner error for the root cause
2. Re-sync/rebuild the module so source maps are regenerated
3. Clear engine cache and retry the module load
4. Update dagger CLI/SDK to matching versions

if enum.SourceMap.Valid && enum.SourceMap.Value.Self() != nil {
    // only then attach
}

if err != nil && strings.Contains(err.Error(), "attach enum typedef source map") {
    // inspect wrapped cause; retry after re-syncing module / clearing cache
}

When it happens

Trigger: The enum typedef carries a valid SourceMap whose underlying object cannot be attached to the dagql server (e.g. its dependencies are not resolvable during attach).

Common situations: Engine-side attach pipeline failure while loading a module whose enum carries source-map metadata; missing dependency results for the SourceMap object.
